C++ 编译C+时遇到错误+；小波库

我在使用g++进行编译时，遇到如下错误：

因为我是一个C++新手，我不知道如何解决这个问题，你介意帮我吗？谢谢

问题在于OpenCV3.X.X中对IplImage的支持要少得多（如果有的话），而您想要使用的小波代码需要此功能

小波示例页面上的以下代码：

 // Creating Image in OPENCV
IplImage *cvImg; // image used for output
CvSize imgSize; // size of output image
imgSize.width = cols_n;
imgSize.height = rows_n; 

不再受支持，也将无法工作，我想这将贯穿整个框架

---

降级到OpenCV2.X.X并重试，或者将小波库更改为支持cv:：Mat的内容。后者是更好的选择，因为C API长期以来一直不受欢迎，而且不受真正的支持。

opencv3删除了IplImage*到cv:：Mat的转换。该小波代码似乎使用了过时的c-api（您可能不应该使用它）。试着找到一个替代的、维护更好的小波库

 // Creating Image in OPENCV
IplImage *cvImg; // image used for output
CvSize imgSize; // size of output image
imgSize.width = cols_n;
imgSize.height = rows_n;
